Abstract：Extreme rainstorm events are increasing with the global climate change and rapid urbanization. Due to the high concentration of economic activities, the responses for flood and waterlogging are more complex in mega cities. Effective early warning and dispatching measures are urgently needed to improve the precision and technology of disaster response. Based on the Digital City Platform of Shenzhen, coupled with multi-source historical, real-time and forecast data, this paper designs and implements a flood and waterlogging early warning and dispatching system in the Hewan Basin. The application-oriented organization mode is adopted in the system, which respectively constructs several scenarios such as flood situation monitoring, situation analysis, simulated dispatching and storm surge risk analysis, aiming at different scenarios such as rainstorm, typhoon and daily monitoring. the system realizes refined simulation and risk evaluation of flood process, and provides support for flood early warning and dispatching decision-making of river basin. This paper introduces the system framework, application process, major functions, key technologies and so on.
